I fixed it. After messing around for quite a big, I figured out it was the events.xml causing the crash. It must've had a syntax error so the game couldn't read it. Anyway, here's the link:

Good news, I've found out when the mod crashes. Every time you transport a patient it crashes. Bad news, I still don't know why it crashes. A few EM4 Modders are helping me out, so the fix is getting closer.
The chief ped is there, he wears a white uniform with a patch on it. Tankers Is a good idea, but I'm planning on changing the map to a more realistic Wheaton Map. I'll see what I can do for parking, and thanks for trying out the mod!
